Description
Technical field
The present invention relates to a kind of aerating system, especially relate to the elliptic annular unit aerating system for sewage disposal.
Background technology
The conventional aeration mode of current biologic process for treating sewage is bottom blast aeration, aeration has and prevents pond inner suspension body sedimentation, and strengthen organism and microorganism in pond, dissolved oxygen contact and make it to strengthen the effect to organic substance decomposing in sewage by oxygenation, but aeration is also the link consumed energy most, account for 50 ~ 70% of whole sewage disposal total power consumption.
Aeration method common in prior art mainly can be divided into two large class, that is: gas bubble aeration method and surface aeration methods.But prior art aerator used often power consumption is large, run and maintenance cost high, and easily there is aeration dead angle.
Secondly, often fix, processing area also fixes by shape for existing aerating system, handiness is not strong, to its operation in the future, safeguard and make troubles, and pipe net arrangement mode is branch network of pipes formula in existing aerating system, it produces larger local losses when system cloud gray model, causes gas blower to consume energy large, therefore needs to find a kind ofly to have the aerating system that coefficient of oxygen utilization is high, power efficiency of oxygen supply is high, handiness is high, energy-conservation.
Aeration process is subject to the great attention of countries in the world field of water treatment and business circles day by day as the core technology in biologic process for treating sewage, along with the requirement of biologic process for treating sewage to aeration process is more and more higher, and be becoming tight the day of the energy, research that is new and effective, less energy-consumption aerator has become promotion sewage disposal cause, environmental protection industry development and energy-saving and cost-reducing important factor.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of elliptic annular unit aerating system, to overcome described defect of the prior art.
Summary of the invention
For solving the problem, the invention reside in and provide that a kind of structure is simple, easy accessibility, aeration be evenly and without the less energy-consumption elliptic annular unit aerating system at aeration dead angle.
For achieving the above object, the technical scheme that the present invention takes is: elliptic annular unit aerating system, comprises aerator, elliptic looped pipeline, connecting tube, water inlet pipe and inlet pipe.Wherein, described aerator adopts to be threaded and is fixed on elliptic looped pipeline, and shape is class reverse taper, and material is ABS plastic; The side surface of described aerator is recessed cone surface, and upper surface is dome sphere, and side surface and upper surface all have pore; Described elliptic looped pipeline is spliced by a left hollow straight pipe, right hollow straight pipe, a hollow semi arch pipe and a U-shaped threeway, and tubing is ABS plastic; With elliptic looped pipeline long axis for line of delimitation, inclined hole is opened outside the pipe of left side He inside the pipe of right side, lower inclined hole is opened inside the pipe of left side He outside the pipe of right side, position of opening is on elliptical center face, upper inclined hole and elliptical center face at 45 °, be directed upwardly, lower inclined hole and elliptical center face is at 45 °, direction down; Described U-shaped threeway is connected with connecting tube, left hollow straight pipe, right hollow straight pipe; Described connecting tube is connected with 4 elliptic looped pipelines, water inlet pipe, inlet pipe.
Elliptic annular unit aerating system of the present invention is further: the upper solarization air cap aperture of described elliptic looped pipeline (2) is 1mm.
Elliptic annular unit aerating system of the present invention also can be: the upper solarization air cap aperture of described aerator (1) is 1mm.
Compared with prior art, elliptic annular unit aerating system of the present invention has following beneficial effect:
1, gas distribution pipe network is designed to elliptic looping network, compared with tree-branch pipeline, 90 ° of elbow quantity reduce by half, and reach the effect reducing local losses, reduce energy consumption, and elliptic looping network security of supply gas are high.
2, monoblock type gas distribution pipe network is designed to modular, conveniently can carries out dismounting and maintenance to it, this modular aerating system can be applicable to the aeration tank of sizes simultaneously.
3, by different with side hole direction in the pipe of right side on the left of elliptic looped pipeline outside pipe, outside the pipe of right side, inside the pipe of left side, bubble makes partial water around elliptic looped pipeline form circulation under impact force action, water body turbulent fluctuation degree can be made to strengthen, bubble is sheared less, gas-water contact area increases, duration of contact also increases, improve the utilization ratio of oxygen, therefore aeration rate can be reduced, reduce energy consumption, meanwhile, add the service area of unit length aeration tube, thus decrease aeration tube use material.
4, class reverse taper aerator side surface and upper surface all open pore, can make water body under aerator also can oxygenation, accomplish aeration evenly, aeration without dead angle, too increase the service area of aerator simultaneously, decrease the consumption of aerator.
The aerating system that elliptic annular unit aerating system is more traditional, can more effectively energy efficient, saving material, and elliptic annular unit aerating system is assembled, simple to operate, easy to maintenance by 4 elliptic looped pipeline monomers.
